Description
Technical field
This utility model relates to a kind of medical appliance; Particularly relate to a kind of Painless blood taking needle that micro blood sample is provided.
Background technology
Safe blood-taking needle is the Medical blood collecting device of taking tip micro blood, is special in take the blood-taking device of tip micro blood sample at medical department, diabetics or other user.
Blood taking needle on current medical market mainly contains two kinds, and one is press-type safe blood-taking needle, and another kind is pressing safety blood taking needle.The triggering start surface of press-type safty pin directly and blood sampling site contact, by pressing safe blood-taking needle, make to trigger start post and be subjected to displacement the inner ejection mechanism of triggering safty pin, inner blood taking needle is launched and get blood, fast retractile after prick skin, after getting blood and completing, by safe blood-taking needle abandon to prevent cross-reference hidden danger, meet the object of disposable use; But these blood taking needle parts are more, and cost is higher.Pressing safety blood taking needle does not directly contact with blood sampling site skin for triggering start surface with the main distinction of press-type safe blood-taking needle, and the hands that triggers the direct contact in start surface user refers to; The end face (non-start surface) of safe blood-taking needle directly contacts with blood sampling site skin, by pressing the triggering start post of safe blood-taking needle, make to trigger start post and be subjected to displacement the inner ejection mechanism of triggering safty pin, inner blood taking needle is launched and get blood, fast retractile after prick skin, after getting blood and completing, by safe blood-taking needle abandon to prevent cross-reference hidden danger, meet the object of disposable use, pressing safety blood taking needle, structure is relatively simple, but pain is large when blood sampling, less stable, production cost is high.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of Stability Analysis of Structures is provided, and cost is low, the little disposable use safe blood-taking needle of keenly feeling.
The technical scheme that this utility model adopts is: a kind of safe blood-taking needle of pressing type, comprises shell, spring members and needle body; Described spring members and needle body insert respectively the two ends of shell, and the protruding key on needle body top embeds the suitable groove of spring members tail end, and spring members and needle body are connected as one.
The both sides of described shell upper end are formed with respectively outer guide groove and interior guide groove, between two interior guide grooves, are formed with cavity; The inner side, middle part of described shell is formed with shoulder; The inside of described interior guide groove is formed with the fixture block of two inclinations; The inner side, lower end of described shell is formed with guide-localization post.
Two outsides in the inside length direction of described spring members upper end are formed with respectively follower rail and interior side rails, between two interior guide grooves, are formed with spring; Described follower rail inserts in the outer guide groove of shell both sides, and the end of interior side rails is formed with barb, inserts in the interior guide groove of shell, and articulates mutually with the fixture block of interior guide groove; Described spring embeds the cavity between two interior guide grooves of shell.
Described needle body is made up of pre-buried staight needle core and plastics; Cantilever end, needle body both sides is formed with the hook being articulated on the shoulder of inner side, shell middle part.
The material of described spring members is plastics.
The beneficial effects of the utility model are: due to upper and lower two-orbit chute design, the movement locus of needle body is smoothly smooth and easy, and stability strengthens, and the pain while contributing to blood sampling is near minimum; , when use, need firmly press down, otherwise the combiner of plastics spring and needle body can not launch release meanwhile, effectively prevent from touching caused maloperation by mistake; These blood taking needle parts are few, cost is low, simple in structure, easy to use, good looking appearance, comfortable feel, can be widely used in health care health industry.

The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail:
As shown in Figures 1 to 4, this utility model blood taking needle, comprises, shell 10, spring members 20 and needle body 30; The two ends that described spring members 20 and needle body 30 insert respectively shell 10, the protruding key 31 on needle body 30 tops embeds the suitable groove of spring members 20 tail ends, and spring members 20 and needle body 30 are connected as one.Two wing structures of described shell 10 have been used for reference the classical configuration design of syringe, more meet medical personnel's operating habit, and easy to use, the both sides of shell 10 upper ends are formed with respectively outer guide groove 11 and interior guide groove 12, between two interior guide grooves, are formed with cavity; Inner side, middle part at described shell 10 is formed with shoulder 15; In described interior guide groove 12, be formed with the fixture block 13 of two inclinations; The inner side, lower end of described shell 10 is formed with guide-localization post 14; The material of described spring members 20 is plastics, and two outsides in the inside length direction of upper end are formed with respectively follower rail 21 and interior side rails 22, between two interior guide grooves 12, is formed with spring, and spring is inserted the cavity between 10 two interior guide grooves of shell; Described follower rail 21 inserts in the outer guide groove 11 of shell 10 both sides, the end of interior side rails 22 is formed with barb, insert in the interior guide groove 12 of shell and articulate mutually with the fixture block 13 of interior guide groove 12, fixed plastics spring members is the initial ejection seat of portion in the enclosure, inside use rear spring parts, the barb of rail end is articulated on fixture block below, form self-locking, prevent from reusing; Described needle body 30 is made up of pre-buried staight needle core and special plastic, and special plastic plays again the effect of protection needle point simultaneously as the carrier of staight needle core; Needle body 30 cantilever ends, both sides are formed with and are articulated in the hook 32 on shoulder 15 inside shell 10 middle parts, and the main body of staight needle core, in the interior slip of guide-localization post 14, guarantees the Stability Analysis of Structures of blood taking needle.
Operation principle of the present utility model is: the end surface that firmly presses down plastics spring parts, plastics spring generation deformation also shrinks the cantilever pressurized of needle body both sides, now, inside the hook of cantilever end, needle body both sides and shell, screens gets loose, plastics spring is also depressed into critical point and is then launched, and plastics spring is launching under active force along launching rapidly and resilience rapidly in upper and lower two chutes inside shell; After safe blood-taking needle launches, plastics spring and needle body can be self-locking in the latched position in housing, can not extract, and prevent reusing of utensil.Plastics spring must firmly press down, otherwise the combiner of plastics spring and needle body can not launch release, has effectively prevented from touching caused maloperation by mistake.
This utility model blood taking needle is because needle body slides in guide-localization post, and stability strengthens; , when use, need firmly press down, otherwise the combiner of plastics spring and needle body can not launch release, reasonable in design has effectively prevented from touching caused maloperation by mistake meanwhile; These blood taking needle parts are few, significantly saved assembling and raw-material cost, and blood taking needle is simple in structure, easy to use, good looking appearance, comfortable feel, are conducive to promote and the extensive use of universal safe blood-taking needle.
It is worthy of note, protection domain of the present utility model is not limited to above-mentioned instantiation mode, needs only those of ordinary skills without process creative work, and the embodiment that can associate all belongs to protection domain of the present utility model.
